While it is contemplatedthat the basicfeatures of the present inventionmay be incorporated in various types of apparatus, the preferred use ofthe invention is in connection with go to make up the devices commonlyreferred to as press boxes. Such devices are employed in tampinz;fibrous is characterized by a tramper member M which reciprocatesbetween per position as shown in solid line in Figure 2 and a lowerposition substantially as shown in may be emptied.

However, when material T is moving through theentrance is the reaction of the material against the feeler arms 68 willmove the feeler arms into a position correspending more or less to thatshown in chain line in Figure 2.

The control grid I26 of tube H2 isconnected into the cathode circuit of tube II2 through a fixed resistorI28 and nected to a contact of previously mentioned door switch I02.

Accordingly, acircuit will be complete through arm 84' of relay 84, through arm of camswitch 10 and through the series connected solenoid valves I8 and 80.

Accordingly, the spray head 64 will not continue to dribble undesiredliquid on the material T.
